Sherman has a history of speaking out. The second-year corner taunted New England quarterback Tom Brady after Seattle’s win over the Patriots on Oct. 14. As a sophomore at Stanford in 2007, he was suspended for one game by Harbaugh for screaming at teammates on the sideline during a loss against Washington.

Today, Sherman went on to echo his NFL coach, Pete Carroll, who noted Harbaugh’s public comments were made a week after he sent out a forceful statement claiming Giants offensive coordinator Kevin Gilbride was attempting to influence officiating. Gildbride had said 49ers defensive tackle Justin Smith “gets away with murder” in holding offensive linemen in advance of the Giants’ win over the 49ers on Oct. 14.

“He’s the same guy who said the other guy was irrational and ignorant for talking about the refs,” Sherman said of Harbaugh.

Now, Harbaugh didn’t call Gildbride those names, but you get the point: It doesn’t sound as if Sherman and his old coach will be exchanging holiday cards in advance of the 49ers’ visit to Seattle on Dec. 23.

Last week, Seahawks wide receiver Doug Baldwin, who also played for Harbaugh at Stanford, seemed to find his former coach’s comments amusing.

“Jim said Sherm and BB were playing too rough,” Baldwin wrote on Twitter. “Hahahahahahahahahahahahahaaahahahhahahahahahahahahahahahahahahahaha”
